The series of spin-off films will be based on Newt Scamander, the fictional author of the Hogwarts textbook 'Fantastic Beasts and Where to Find Them.'

Warner Bros. announced Sept. 12 that the studio will make a series of spin-off films set in J.K. Rowling’s magical world. However, fans shouldn’t expect to see appearances by Harry and his friends.

Rowling said the new project is “neither a prequel or a sequel, but an extension of the wizarding world” that will focus on the adventures of Newt Scamander, the fictional author of “Fantastic Beasts and Where to Find Them,” the textbook used in Hogwarts’ Care of Magical Creatures class.

The 42-page “textbook” was published in 2001 after the fourth Harry Potter novel. Rowling wrote it to give fans a deeper look at Harry’s world and to raise money for Comic Relief U.K.

The “Fantastic Beasts and Where to Find Them” movies will be an original story and will mark Rowling’s foray into screenwriting.

“I thought it was a fun idea, but the idea of seeing Newt Scamander, the supposed author of ‘Fantastic Beasts,’ realized by another writer was difficult,” Rowling said.

“Having lived for so long in my fictional universe, I feel very protective of it and I already knew a lot about Newt. As hardcore Harry Potter fans will know, I liked him so much that I even married his grandson, Rolf, to one of my favorite characters from the Harry Potter series, Luna Lovegood.”

Rowling has revealed little about the movie, but she did say that Newt’s story will begin in New York, 70 years before Harry Potter is born.

What we know from the book “Fantastic Beasts” is that Newt is a magizoologist — a person who studies magical creatures — and he researched and wrote the text between 1918 and 1927.

There’s speculation across social media that the film will follow Newt as he gathers information on magical creatures and writes his famous guide, which classifies 75 beasts from X (boring) to XXXXX (known wizard killer/impossible to train or domesticate).

Of the 11 creatures noted to live in America, none rate higher than XXX; however, dragons can be found worldwide, so it’s likely Newt could encounter some seriously dangerous beasts in New York.

And while fans won’t see any Harry, Ron or Hermione, they might get to glimpse a familiar face. Albus Dumbledore was a friend of Newt’s and wrote the introduction to “Fantastic Beasts,” so we could see a cameo from a young Dumbledore.
